Answer 1

Here is an function that will sum all your time values in format HH:MM:

function sum_time() {
    $i = 0;
    foreach (func_get_args() as $time) {
        sscanf($time, '%d:%d', $hour, $min);
        $i += $hour * 60 + $min;
    }
    if ($h = floor($i / 60)) {
        $i %= 60;
    }
    return sprintf('%02d:%02d', $h, $i);
}

// use example
echo sum_time('01:05', '00:02', '05:59'); # 07:06
